Global market expected to grow from $66.53 billion in 2025 at a CAGR of 6.87% through 2030
The global wastewater treatment services market is projected to reach $92.74 billion by 2030, rising from $66.53 billion in 2025 at a compound annual growth rate (CAGR) of 6.87% between 2025 and 2030, according to a new market report.
The report, Wastewater Treatment Services Market by Service Type (Design & Engineering Consulting, Building & Installation, Operation & Process Control, Maintenance & Repair, and Other Service Types), End-Use Industry (Municipal, Industrial (Chemical & Pharma, Oil & Gas, Food, Pulp & Paper, Metal & Mining, Power Generation)), and Region - Global Forecast to 2030, examines the market across service types, end-use industries and regions.
Environmental Concerns and Urbanisation Drive Demand
The report identifies increasing environmental concerns, rapid urbanisation across major economies and stricter regulatory frameworks as key factors driving demand for wastewater treatment services.
Population growth and expanding industrial activity have contributed to rising wastewater volumes from domestic, commercial and industrial sources. This is increasing the need for wastewater treatment systems aimed at addressing environmental impacts and public health requirements.
Growing awareness of water scarcity is also contributing to the adoption of wastewater recycling and reuse technologies.
Reduce, Recycle and Reuse Create Market Opportunities
The report highlights the three Rs of sustainability — reduction, recycling and reuse — as an opportunity for organisations seeking to reduce waste and conserve natural resources.
Treated wastewater can be reused for applications including industrial processes, toilet flushing, landscape and agricultural irrigation, and groundwater recharge. Such water recycling can help conserve water and resources, while wastewater treatment systems can be adapted to meet the quality standards required for different reuse applications.
The report notes that water remains essential for businesses, while regulatory requirements can limit the supply available for municipal and industrial use.
